Problems solved by technology

However, at present, the error tolerance rate of two-dimensional codes generally does not exceed 30%. If the one-dimensional code covers too many two-dimensional codes, the two-dimensional code may not be recognized. If the size of the one-dimensional code is too small, it may be one-dimensional. code not recognized

Embodiment approach

[0038] In another embodiment of the present application, the information invalid area is set as a hollow area of ​​the information valid area. In this implementation manner, the second sub-pattern code may be completely surrounded by the first sub-pattern code. Such as image 3 As shown, compared to the fully filled square two-dimensional code in the related art, the middle of the two-dimensional code provided by the embodiment of the present application can be a hollow area, which is an invalid area for information, and can be used to accommodate barcodes, etc. Two sub-graphic codes. Of course, multiple second sub-pattern codes can be accommodated in the same information invalid area, and a plurality of disconnected hollow areas can also be set in the first sub-pattern code, and each hollow area can also be used to accommodate At least one second sub-pattern code.

[0039] It should be noted that the setting method of the effective information area and the invalid informat...

Abstract

The invention relates to a graphic code, a graphic code encoding method and a graphic code decoding method. The graphic code comprises a plurality of sub-graphic codes, in the sub-graphic codes, a first sub-graphic code comprises an information effective area and an information ineffective area, and the information ineffective area is used for accommodating at least part of a second sub-graphic code. According to the graphic code, the graphic code encoding method and the graphic code decoding method provided by the embodiment of the invention, the same graphic code can express various kinds of information, different sub graphic codes do not cover the information of each other, and the integrity of the information of each sub graphic code is kept.

Description

technical field [0001] The present application relates to the technical field of data encoding, in particular to graphic codes, graphic code encoding methods and decoding methods. Background technique [0002] At present, graphic codes have been widely involved in all aspects of people's daily life, especially QR codes, which are typical application scenarios such as information acquisition, website redirection, advertisement push, anti-counterfeiting traceability, account login, mobile payment, membership management, etc. Although two-dimensional codes are very popular at present, one-dimensional codes, especially barcodes, are still widely used in various application scenarios, such as commodity barcodes, book barcodes, weighing barcodes, and so on. Moreover, with the continuous development of coding technology, other types of graphic codes may also appear. Therefore, setting multiple graphic codes on the same object is unavoidable. [0003] In related technologies, ther...
